A Taste For Death (6)

Dalgliesh visits the church where Berowne was killed and is surprised when Father Francis finds a button in the offerings box. Emily Wharton thinks it must have been young Darren who put it there instead of the 10 pence she had given him to go and light a candle. The Berowne's cook, Miss Matlock, clearly recognizes the button but says she can't recall where she's seen it. Halliwell the chauffeur tells Dagliesh that he drove Sir Paul's mother to the church on the evening her son was killed.
